Major Crimes Unit Starts with Police Academy Students

"accept,"

"Ding! Congratulations, host, you have acquired the beginner-level pressure hemostasis technique, perfect-level observation skills, and master-level crowd control ability."

He then quickly said to Li Dawei, who was standing beside him.

"Dawei, you and the supermarket security guards will guard the exits and not let anyone out."

Li Dawei quickly agreed.

"Okay, Mingcheng,"

Fortunately, this supermarket wasn't very big, with only one exit for one customer.

As long as the security is maintained, no matter what happens, it will be difficult for the suspect to leave the supermarket.

Li Dawei immediately ordered several security guards to guard the entrance, prohibiting anyone from entering or leaving.

Then, Wu Mingcheng went to the counter, picked up the supermarket's loudspeaker,

"Hello everyone, we are police officers. A case has occurred inside the supermarket. Please remain where you are and do not panic. We will resolve the situation quickly."

At that moment, a young man wearing a baseball cap frowned in a corner of the supermarket.

He thought to himself, "I haven't even managed to escape yet, and the police are already here? This is different from what I expected. How did the police arrive so quickly?"

If he had known there were police officers inside the supermarket, he probably wouldn't have chosen to commit the crime there.

However, he wasn't too worried. He deliberately chose to commit the crime in a blind spot of the surveillance cameras, making it difficult for ordinary police officers to catch him.

At this moment, Wu Mingcheng rushed to the corner where the incident had occurred to check the situation.

He immediately spotted a stylish girl sitting on the floor, clutching her thighs in obvious pain.

Blood continued to seep from between her fingers, indicating a serious injury.

When the crowd saw Wu Mingcheng arrive in his police uniform, they exclaimed.

"The police are here,"

“Police Officer Tongzhi, you’ve finally arrived,”

"What should we do?"

……………………………………………………………

Wu Mingcheng addressed the onlookers,

“All of you step back,”

After everyone stepped back, Wu Mingcheng knelt down and carefully separated the girl's hands.

Upon examining the wound and noticing the girl's bleeding, he deduced that it had been caused by a sharp blade, and that it was highly likely that a major artery in her leg had been severed.

Given the extent of the bleeding, we must stop it first.

Otherwise, even if an ambulance arrives, the girl could be in danger due to excessive blood loss.

Fortunately, the system reward included the pressure-based hemostasis method; otherwise, today would have been quite troublesome.

He had only learned basic first aid at school, and even he was helpless in this situation.

He immediately shouted at the several stunned sales clerks in their supermarket uniforms, "What's wrong?"

"Go get some gauze and bandages right away; we need to stop the bleeding immediately,"

The supermarket sells gauze bandages. A sales clerk, startled by Wu Mingcheng's shout, hurriedly went to get them.

Chapter 524 Serial Killer?

At this moment, Wu Mingcheng was like a seasoned emergency doctor; the method of applying pressure to stop the bleeding was already in his mind.

He kept pressing on the arterial pulsation point near the heart at the site of the bleeding artery with his fingers, which could slow down the bleeding.

Sure enough, the bleeding from the wound, which was initially flowing heavily, slowed down considerably.

The onlookers, upon seeing this, couldn't help but breathe a sigh of relief.

This young police officer was definitely an expert at stopping bleeding; otherwise, he couldn't have just casually pressed on the wound and immediately reduced the heavy bleeding.

With Wu Mingcheng as their pillar of support, everyone's mood stabilized, and they began to cooperate with Wu Mingcheng in doing what they could.

The gauze bandages arrived quickly.

Wu Mingcheng used a local pressure bandage to stop the bleeding, which is similar to the finger pressure method. It involves applying pressure to the pulsating point proximal to the heart of the artery.

The gauze bandage is simply more secure and distributes the force more evenly.

Wu Mingcheng then covered the wound with sterile gauze and used a bandage to secure and compress the pulsating point.

The bleeding from the girl's wound gradually stopped.

Everyone was astonished by what they saw, and they all cheered in unison.

"Well done, young man,"

"These young people nowadays are really capable,"

"No wonder he's a policeman,"

.........................................................

A little boy, seeing that the girl's bleeding had stopped, excitedly clapped enthusiastically for Wu Mingcheng.

"Officer, you're amazing!"

Although the crowd didn't understand medicine, they knew that as long as the girl's bleeding stopped, her life would be saved.

Gradually, the girl's pale complexion regained its rosy hue.

Only then did she raise her head to look at the policeman who had saved her life, carefully observing Wu Mingcheng.

The situation was urgent, and she hadn't looked closely. She hadn't expected the policeman to be so handsome; he really was.

She expressed her heartfelt gratitude to Wu Mingcheng.

"Thank you, handsome policeman."

Wu Mingcheng nodded.

"Okay, the bleeding has basically stopped. When the ambulance arrives, you'll go with it to the hospital for a thorough check-up."

The girl smiled sweetly.

"Yeah, I get it,"

Wu Mingcheng then turned on the walkie-talkie and asked Li Dawei,

"Dawei, you didn't let anyone out, did you?"

Li Dawei responded.

"Mingcheng, don't worry, this supermarket only has one exit, and I've kept a close watch on it; no one has gone out."

Hearing Li Dawei's answer, Wu Mingcheng finally breathed a sigh of relief.

He then looked down and asked the girl.

"Did you see who cut you?"

The surrounding crowd immediately fell silent. This murderer had dared to commit such a crime in broad daylight, and in a crowded place like a supermarket—it was utterly audacious!

Everyone was both angry and anxious, hoping the girl could provide evidence so the police could catch the murderer.

After all, everyone worries that while they're out shopping, a murderer might suddenly appear and hurt them.

To everyone's surprise, when the girl heard Wu Mingcheng's question, she shook her head blankly.

"I didn't see it; I just felt a sudden, intense pain in my thigh, and that's when I realized I'd been cut."

The girl felt ashamed that she didn't even know who had hurt her.

After hearing the girl's words, it's basically impossible to learn anything about the murderer from her.

A thoughtful look appeared in Wu Mingcheng's eyes as he recalled the girl's wound.

Based on his skills in on-site investigation and reasoning, he still managed to discern some clues.

Normally, people hold knives with their right hand, but based on the location, direction, and depth of the injured girl's wound,

He concluded that the murderer used his left hand to hold the knife.

Because all the characteristics of the girl's wound could only have been caused by holding the knife in her left hand.

In other words, the murderer is very likely left-handed.

Could the killer be left-handed? Was the victim a girl? Could it be that serial killer?

He was suddenly startled, and suddenly remembered the notice issued by the Municipal Bureau. Wasn't this exactly the characteristic of a serial killer?

He immediately turned on the walkie-talkie and emphasized to Li Dawei,

"Dawei, your chance to make a contribution has arrived. Under no circumstances can you let anyone out, understand?"

Li Dawei responded immediately.

"Mingcheng, don't worry, I'm still waiting to get some credit for this."

Then, Wu Mingcheng turned to the sales clerk beside him and asked,
